Pure Pascal MEM MEMW

Post by artik-wroc »

How to read a byte from a specific address (e.g. $12345) ?
There is a STPASCAL library in Maxon Pascal which has PEEK and POKE.
Pure Pascal..... ???

In the same way you would do it in C. By having a pointer of the appropriate type pointing to the address you like to write/read:

Code: Select all

program peekpoke;

type PLongInt = ^LongInt;

begin
	PLongInt($10000)^ := 42;
	writeln(PLongInt($10000)^);
end.

Thanks. A simple example works. I still have a problem with write to the card registers. I'll have to check it out, maybe I made a mistake somewhere.

EDIT: It depended on compiler settings and it's working now :)
